Special-shaped bag types

As society's demand for plastic flexible packaging continues to increase, plastic flexible packaging continues to cover the market with its inherent characteristics of bright colors, novel patterns, and ease of use. The market has also put forward higher requirements for plastic flexible packaging, which not only requires innovative designs to attract more people's attention, but also requires high barrier properties to maintain the freshness of the contents. This also requires the shape of the soft bag to be ever-changing, so as soon as the special-shaped bag came out, it quickly attracted people's attention with its unique shape and distinctive personality. This article briefly introduces the production of special-shaped bags and the performance of related equipment for reference by flexible packaging companies:

1. Types of special-shaped bags

1. The special-shaped bag is sealed on three sides, and various patterns are directly punched and cut on the three-sided sealing bag to meet the requirements of daily chemical products, food, etc., and reflect the intuitive and vivid characteristics of the product. For example, various fruit slice packaging bags are designed according to the shape of the fruit.

2. Self-standing special-shaped bags, through bottom filling, can make special-shaped bags of various shapes stand up, fully reflecting the three-dimensional effect of special-shaped bags, and convenient for display on shelves in supermarkets or shopping malls.

3. Self-standing special-shaped bag with its own zipper. With the zipper, the bag can be opened repeatedly according to the unique shape of the special-shaped bag. It is generally suitable for some light dry goods, such as candies, dried fruits, chocolates, biscuits, jelly, tea, etc.

4. Use a self-supporting special-shaped bag with a nozzle for easy dumping of contents. Products with nozzles can be sealed repeatedly, which means they can be opened and used multiple times. This special-shaped bag is suitable for liquid beverages, shower gel, shampoo, ketchup, cooking oil and other liquid products that need to be opened multiple times.

2. Special-shaped bag manufacturing and equipment. In some flexible packaging companies, special-shaped bags are formed by a bag making machine, punched offline with a punching machine, and the special shape is cut off, and then necessary trimming is performed. This method wastes a lot of manpower and material resources, and the production efficiency is not high. At present, the auxiliary equipment of the bag making machine is a die-cutting machine, which is specially used for the production of special-shaped bags. Mainly driven by servo motor, equipped with light, electricity and gas. With the PLC signal, it can be well connected with the bag making machine to achieve online synchronous die cutting and ensure the bag making accuracy of special-shaped bags. There is no need for offline subsequent processing, and it has functions such as online delivery of finished products, edge trimming, and automatic winding, which greatly improves the efficiency of making special-shaped bags.

Special-shaped bags break through the constraints of traditional square bags and change the straight edges of the bags into curved edges, reflecting different design styles. They are novel, simple, clear, easy to identify, and highlight the brand image. They also represent the trend of plastic flexible packaging. Trend direction. At present, some large domestic flexible packaging companies have been equipped with corresponding special-shaped bag production equipment. It is believed that with the development of bag making technology and equipment and the popularization of die-cutting equipment, the manufacturing of special-shaped bags will no longer be a problem for flexible packaging companies, and special-shaped bags will bloom everywhere.
